Water molecules are dipolar - they have both positively charged and negatively charged regions due to differences in the electronegativity of atoms (this is how strongly they attract electrons). This propert...

It can seem tricky to integrate ln(x), as there is no obvious solution to do it.It is, however, quite simple to do if you use the 'by parts' method.If you have y=ln(x)Set u=ln(x) and dv/dx=1That gives du/dx=...

Stationary point: dy/dx = 2e^2x - 11e^x =0 2e^2x = 11e^x e^x=5.5 (can divide by e^x since e^x > 0 for all x) x=ln(5.5), y=5.5^2-11 5.5+24=-6.25 Answer: (ln(5.5),-6.25) Nature of stationary point : Evaluat...

DNA Helicase unwinds double helix by breaking hydrogen bonds where the gene is located.The single stranded part of the helix will act as template strand for RNA.Free floating nucleotides will attach to compl...
